UK SD-WAN Comparison Guide + Filter Requirements

Arista VeloCloud distinguishes itself with Dynamic Multipath Optimisation (DMPO), which continuously monitors link quality to sub-second standards. This technology remediates packet loss and jitter on the fly, making it an excellent choice for enterprises relying on standard broadband.

Cato Networks creates a seamless global fabric where all security and networking capabilities are converged into a single cloud service. This architecture eliminates the need for branch appliances, allowing traffic to be inspected and optimised at the nearest PoP location.

A result of their 2017 Viptela acquisition, Catalyst offers purpose-built architecture separating control, data and management planes for greater scalability. Furthermore, cloud-hosted or on-premises vManage deployment options suit various security requirements and offer easy integration with the broader Cisco security portfolio.

Meraki heavily prioritises ease over features, with AutoVPN establishing site-to-site connectivity without manual configuration. Visual slider controls prioritise applications without understanding bandwidth percentages or DSCP markings, enabling network management without formal networking training.

Integrates security and networking through FortiGate’s purpose-built ASIC processors to enable deep packet inspection, SSL decryption and IPS simultaneously. Security processing happens locally at branch sites with no backhauling, ideal for regulated sectors requiring on-premises security control.

Integrates HPE Aruba’s EdgeConnect WAN optimisation with Juniper’s Mist AI and Session Smart Routing. This combination identifies applications from the first packet whilst simultaneously using conversational AI for troubleshooting.

Prisma utilises Instant-On Network (ION) edge devices connecting to a cloud security platform for native SASE convergence. This convergence suits UK enterprises already invested in Palo Alto's NGFW products, providing unified policy management across firewalls, SD-WAN and cloud security.

The VOS (Versa Operating System) can be run on commodity white-box hardware, virtual machines or cloud instances, offering great flexibility. UK financial services often leverage this for regulatory compliance - separate trading floor, corporate network and third-party access with zero traffic leakage.

Partnering with the likes of Palo Alto Networks, Zscaler and Radware for security services, Aryaka’s service model is fully managed with integrated connectivity. The SmartConnect service dynamically selects optimal paths using real-time monitoring and application-aware routing, with built-in WAN optimisation including TCP acceleration.

BT’s Service model can be either fully managed or co-managed with UK-based 24/7 support and security-cleared engineers. BT also supports running SD-WAN alongside existing MPLS circuits during transition periods, enabling gradual cutover reducing migration risk.

GTT owns their physical network across more than 600 data centres worldwide - enabling fewer hops and lower latency than competitors leasing lines. GTT’s infrastructure ownership delivers deterministic performance for international traffic with faster fault resolution across borders compared to providers relying on third-party circuits.

It’s worth noting that Virgin does not operate a global backbone and therefore uses public internet gateways combined with Virgin's UK fibre underlay. Where competitors rent circuits from BT Openreach, Virgin Media O2 troubleshoots and repairs their own infrastructure reducing resolution times.

This mobile-first approach distinguishes Vodafone from fixed-line carriers - organisations with mobile workforces and IoT requirements benefit from integrated cellular connectivity. UK field service organisations - utilities, logistics, emergency services - leverage Vodafone's cellular capabilities for van-based connectivity.
